Measuring TCP Tail Loss Probe Performance
André Ryll · TU München - Informatik · 2014
This paper analyzes the performance of the TCP Tail Loss Probe algorithm proposed by Dukkipati et al. in February 2013 under various virtual network conditions. To provide accurate and repeatable measurements and varying network conditions the mininet virtual network is used. Variations include the available bandwidth, round trip time and number of tail loss segments. The tests are done by requesting HTTP data from an nginx web server. Results show that TLP is able to decrease the total transfer time in high-speed networks by 38% and the time until data is retransmitted by 81%. These improvements decrease significantly for higher delay links.
